CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 745,265, dated November24, 1903.

Original applicatiln led May 29, 1902, Serial No. 109,477. vDivided andthisI application filed May 2, 1903. Serial No. 155.250,

(No model.)

T0 all wtorn it 17m/y concern.-

Be it known that I, CLINTON A. TOWER, of Cleveland, Cuyahoga county,Ohio, have invented a new and useful Car-Ooupler,of which the followingis a ful1,clear,and exact description,reference being had to theaccompanying drawings, forming part of this specification, in which*Figure l is a horizontal section of a coupler embodying my invention.Fig. 2 is a similar view showing the knuckle open. Fig. 3 is a verticalsection of the coupler.

In the drawings, 2 represents the couplerhead, and dis the knuckle,whosetail 3 eX- tends rearwardly from the pivot-pin 4. The coupler has alocking and opening piece 5, the construction and operation of which areexplained in an application. filed by me on May 29, 1902, Serial No.109,477, of which this application is a division. Vhen the coupler islocked, this piece fits against the forward side of the knuckle-tail, asshown in Fig. 1.

As a protection against displacement of the knuckle in the event ofbreaking or loss of the pivot-pin I Aform on the rear side of theknuckle-tail, near the position of the pivot 4, a recess 13, taperingoutwardly' toward the head of the knuckle, and I form on thecoupler-head, near the outer end thereof, a projection 14, adapted toenter and interfit with said recess. The recess in the knuckle isforward of the middle of the knuckle-tail and does not extend to the topand bottom surface thereof, since if it did so the knuckle y would beweakened. The rear end wall of the recess inclines forwardly andoutwardly, but on a line eccentric to the axis of the knuckle, so thatwhen the knuckle is opened the rear surface of the recess immediatelyleaves its bearing on the back of the projection 14, and when theknuckle is closed the said rear surface finds its seat Without slidingon the projection. The knuckle therefore closes with freedom.

By locating the projection and recess near the position of the pivot-pininstead of locating them at the inner end of the tail it is easier tofit them together, and when under draft all tendency of the one to pullaway from the other is avoided. Even without the pin the knuckle is heldin place with the greatest security. This device also serves'to takestrain from the pivot-pin when the p'in is intact, and thus preventsbending of the pin.

I claiml. A coupler having a swinging knuckle, a recess in the rear sideof the knuckle-tail, situate forward of the middle of the tail andterminatingshort of the top andbottom surfaces of the knuckle, and aprojection on the coupler-head adapted to enter the recess;substantially as described.

2. A coupler-knuckle having on the outer side of its tail, forward ofthe middle thereof, a recess adapted to receive a projection on thecoupler-head, said recess terminating short of the top and bottomsurfaces of the kn uckle,

substantially as described. l

3. A coupler-knuckle having on the outer side of its tail, forward ofthe middle thereof, a recess terminating short of the top and bottomsurfaces of the knuckle and adapted to receive a projection on thecoupler-head, vsaid recess tapering toward the head of the knuckle andhaving its rear end wall forwardly and outwardly inclined on alineeccentric to the axis of the knuckle; substantially asdescribed.

In testimony whereof I have hereunto set my hand.

CLINTON TOWER.
